Setting up evreything seems to work, but if I execute/run the tool via 'auto-py-to-exe' I got:

I went through all documentation I found online but got no idea what the root cause could be.

Looks like something wrong with PyInstaller. Have you tried reinstalling it?

Interesting, I tried with a new installed version of python (x,y) (https://python-xy.github.io/downloads.html) via 'pip install auto-py-to-exe' with the same error.

Then I created a new a virtual environment and manually installed pyinstaller ('setup install') because via pip I always run into trouble. In this clean virtual environment 'pip install auto-py-to-exe' gives me finally a working version.

If you call from PyInstaller import __main__ in the environment that wasn't working, do any errors appear?

Ok, thank you for this. Since the error occurs outside of auto-py-to-exe then this is not an issue with auto-py-to-exe.

If you're able to setup a guide showing people how to reproduce this error, you could report it to PyInstaller and see if they have any clue what might be causing this.

Also thank you for bringing this up!

No problem.
Meanwhile I found out using the previous version of pyinstaller went fine.
I put not so much attention to the fact that I also has problem installing pyinstaller (3.4.1) via pip. But with 'python -m pip pyinstaller==3.3.1' everything is fine and also 'auto-py-to-exe' runs in my 'normal' environment.

It seems to be that issue:
